Years ago, after someone managed to dump a piano on it's back in an almost local high school, liquefying a student's foot as a result, I put a set of dollies under a P22 for them. Bolted and lagged in good and solid, I thought maybe we had it cornered. Nope. Next year, I went back to tune the pianos, and found that they had unsuccessfully attempted to ramp jump the dollied piano across a threshold at high speed. When I saw it, they had already had the maintenance genii weld the casters back on, badly charcoaling the back of the piano above both sets of joints. "No problem, we fixed it ourselves". They're ingenious, and there are a whole lot more of them out there than there are techs. Ron N
